To ensure safety of people needing to service a low-voltage network of an electric power distribution system, dwellings being connected to this network may include autonomous units for producing electricity, thus generating voltage and endangering the people servicing the work. Data are obtained from consumption records from the meter of each dwelling, in regular time intervals, and meteorological data are also obtained in the geographical area of these dwellings, in order to identify at least some weather conditions conducive to the production of energy by autonomous units. A model is then applied for detecting, based on the first and second data, a coincidence between periods of lower consumption measured by a meter and weather conditions conducive to electricity production by autonomous units during these periods. Therefore, information on the presence of autonomous units in the dwelling can be deduced and given to people before their servicing.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method according to claim 1, wherein the server further obtains an instantaneous measurement of the voltage in the low-voltage network before the servicing work, and the work is dependent on the server obtaining a zero-voltage measurement in the low-voltage network.
5. The method according to claim 4, wherein a cross-validation is further applied in order to consolidate the determination of the calculation model.
8. The method according to claim 1, wherein the autonomous production means whose presence is to be detected is a photovoltaic panel, and wherein the weather conditions include at least the level of sunlight at a given moment.
13. A processing circuit of a server according to claim 12, comprising a memory for storing the database and a processing circuit configured for applying the model for detecting autonomous production means in a dwelling, based on at least the first data on consumption from the meter of that dwelling and on the second data on weather conditions for the area of the dwelling.
